The CS1708A 8-Port PS/2-USB KVM Switch from ATEN is a control unit that allows access to multiple computers from a single PS/2 or USB console (keyboard, mouse, and monitor). A single switch can control up to eight computers. As many as 31 additional switches can be daisy-chained to each other, so that up to 256 computers can all be controlled from a single keyboard-monitor-mouse console. Additionally, a front panel USB port is available for each computer to access any peripherals connected to it on a one-at-a-time basis. Its dual interface supports computers and console with PS/2 or USB keyboards and mice. This switch requires no software installation and is suitable for convenient computer selection via front panel pushbuttons, hotkeys, and multilingual On-Screen Display (OSD) menus.
